Red Seal Glazier Practice Exam

Describe the term "Glazing Compound."

1. A rigid material used to frame glass

2. A flexible material used to seal and hold glass in place

3. A type of adhesive used for glass bonding

4. A decorative border for glass panels

The correct answer is: A flexible material used to seal and hold glass in place

The term "Glazing Compound" refers specifically to a flexible material used to seal and hold glass in place. This type of compound is applied around the edges of glass panes, especially in windows, to provide a weather-tight seal that protects against moisture and air infiltration. Its flexibility is crucial because it allows for expansion and contraction due to temperature changes without cracking or breaking the bond with the glass or the frame. The glazing compound also serves to cushion the glass, minimizing the likelihood of breakage from vibrations or impacts. It is essential for maintaining the integrity of the installation and ensuring that the glass remains securely in place over time. This function distinguishes it from other materials that may be rigid, decorative, or focused on adhesion without considering the dynamic nature of the glass and its installation environment.
